This problem is frequently posted on this board and you did not obey the guidelines for posting a problem report, so do not be surprised that nobody reacts anymore.

By now it is wellknown that many screens, especially TV sets with PC-input, provide incorrect EDID data. This is caused by the limitations of the EDID system as well.
Unfortunately NVIDIA obeys the EDID data as if it were the only truth, and discards your directions to use the correct resolution (1920x1080).

See the driver README and other threads on this board for ways how to work around this.
